LAKE BUTLER, FL (RNN) - Three people died, including the gunman, after a deadly shooting at two locations in north Florida on Saturday.

Union County Sheriff Jerry Whitehead identified the gunman as Hubert Allen Jr. The sheriff said Allen was the step-grandfather of Buffalo Bills and former Clemson running back C.J. Spiller, who is a native of Lake Butler.

Allen, 72, shot four other people including his former employer before taking his own life at his home, according to officials.

"We are looking at some things that might give us an indication there was some type of anger, but as we speak right now, no, I don't have anything ironclad. We're working on some things," Whitehead said.

The first shooting happened just before 9:30 a.m. at Pritchett Trucking. The first victim, identified as David Griffis, 44, was last reported in critical condition at a Gainesville hospital.

Allen followed the trucking company's owner, 80-year-old Marvin Pritchett, to his farm and fatally shot Pritchett while he was sitting in his truck. The gunman also shot 66-year-old Lewis Mabrey Jr., who survived.

Allen fatally shot Rolando Gonzales Delgado, 28, at the ranch before going home and turning the gun on himself, according to Whitehead.

"I knew all the individuals personally; in fact, Mr. Pritchett is my uncle," Whitehead said. "All the people involved, Mr. Allen knew all of them. We're totally shocked. The community is in shock.

"Mr. Pritchett has been such a big part of our community, helping with our school and programs. He's a man who's a self-made millionaire, just a great guy."

Spiller - who graduated from Union County High School - finished his career at Clemson with 3,547 rushing yards and 32 touchdowns, including 1,212 yards and 12 TDs his senior year in 2009.

His third season in the NFL was his best as he rushed for 1,244 yards and scored six touchdowns last year.
